Cadmium ion removal by electroflotation onto sewage sludge biomass
Non–living, anaerobically digested, Activated–Sludge (AS) was examined (laboratory–scale experiments) as possible biosorbent for the removal of cadmium from dilute aqueous solutions. The application of electroflotation to the suspended biomass, was investigated in this paper as an effective solid/liquid separation technique for the metal–loaded biosorbent particles. The main parameters ...

Dewatering waste-activated sludge using dissolved gas-flotation followed by filtration
After the successes of flotation of waste-activated sludge (WAS), using the new technique utilizing CO2 gas as well as using model gas (80% N2+20% CO2) in previous research because of the high water solubility of CO2 gas, the aim of this study is to develop a simple method for dewatering WAS for easier reuse and safe disposal. The paper introduces a laboratory model for dewatering WAS in two ...

Benefits of Electrocoagulation for Remediation of Refinery Wastewater
Refinery Wastewater: Benefits of Remediation by Electrocoagulation Crude oil is a fossil fuel formed from long-dead organisms subjected to intense heat and pressure underground. This resource is the main ingredient in the production of gasoline, diesel fuel, lubricants, kerosene, propane, and asphalt. All of these products can be made in a single refinery through a complex branching series of ...
